Cause of death

Mechanical asphyxia

AI-generated summary

Eli Tan Marnock, aged 2 years, died from mechanical asphyxia when a tree fell onto his family home during a storm on 28 February 2015. The tree fell despite appearing healthy with no obvious signs of instability. An independent arborist concluded that windthrow could not have been anticipated by ordinary inspection, as root damage may have occurred after any inspection and underground structural issues are not detectable from above-ground assessment. The coroner found no preventable factors, as the tree's failure was due to exceptional wind conditions (44 km/h gusts) on a healthy-appearing tree. However, the finding endorses council initiatives for community reporting of hazardous trees and assessment of trees with high target values near buildings, emphasizing that tree inspection systems should identify potentially dangerous trees before catastrophic failure occurs.

FINDING INTO DEATH WITHOUT INQUEST

form 38 Rule 60(2) Section 67 of the Coroners Act 2008

I, PETER WHITE, Coroner having investigated the death of ELI TAN MARNOCK

without holding an inquest: find that the identity of the deceased was ELI TAN MARNOCK born on 9 January 2013 and the death occurred on 28 February 2015 at 7-9 View Road, The Patch, Victoria from: 1 (a) MECHANICAL ASPHYXIA

Pursuant to section 67(1) of the Coroners Act 2008, there is a public interest to be served in

making findings with respect to the following circumstances:

  1. Eli Ian Marnock was 2 years of age at the time of his death. He resided in The Patch, with his parents, Stefan Marnock and Suzanne Surridge, and siblings, Jackie and Nicola. Eli's grandparents, Russell Surridge and the late Thelma Surridge, and his uncle, Mark Surridge, also lived in the house.

  2. Eli and his immediate family resided in the downstairs area at the front of the house, whilst his grandparents and uncle resided upstairs, in the rear of the residence. The house itself, was a three storey structure that was made from timber and fibro cladding. It had five bedrooms and three living areas.

  3. On 28 February 2015, the entire family, with the exception of Jackic, were at home. Mr Marnock’s son from a previous relationship, Jessie, was also at the residence. The family had originally planned to attend the Knox Festival fireworks, however, decided not to go, due to the unpredictability of the weather that evening.

  4. At approximately 7:00pm, Eli was placed in his cot in the bedroom situated on the lower floor, at the front of the house.

  5. At approximately 8:54pm, a storm hit the Ferny Creek area.! Emergency services were inundated with calls from police communications to attend incidents involving fallen trees and traffic incidents as a result of the storm. The Bureau of Meteorology identified that the wind speed at this time was 21km/hr, with a wind gust speed of 39knv/hr.? As the wind started to pick up, the power flickered throughout the house. Mr Marnock located torches whilst Mr Surridge went upstairs to close the curtains in his bedroom. Mr Marnock proceeded to the front door to check on Mr Surridge’s welfare. It was at this time that he felt the house rumbling; then shaking in its entirety. Mr Marnock was then knocked to his knees upon the ceiling collapsing. Ms Surridge was next to him at the time. The couple did not sustain any injuries. They started to look for their children.

  6. Nicola was located sitting on a chair in the lounge room. She was pinned down by a beam from the roof lying across her chest, Mr Matnock attempted to lift the beam off Nicola. He was unable to do so. He then instructed Ms Surridge to get the hi-lift jack from the car, in an attempt to use it to lift the beam off Nicola. Upon following Mr Marnock’s direction, Ms Surridge observed that she was unable to get to the car, as the carport had also collapsed. It was at this time that she discovered that a tree had fallen onto the house.

  7. Between 8:54pm and 9:00pm, the greatest wind speed of the storm was 21km/hr, with the greatest wind gust speed being 44 km/hr.? According to the Bureau of Meteorology’s Beaufort Wind Scale,* the wind gust speed equated to the Beaufort Scale Number of 6 with the descriptive term of ‘strong winds’.°

  8. At9:00pm, it started to rain, According to the Bureau of Meteorology, the rain fall measured 0.2mm.°

  9. At9:0lpm, upon returning to the house, Ms Surridge called ‘000’, whilst Mr Marnock instructed an unscathed Jessie, to run up the street to seek assistance from the neighbours. It was at this time that Mr Marnock discovered that Mr Surridge was unhurt, however, trapped in his bedroom upstairs. Ms Surridge remained with Nicola in the lounge room whilst Mr Marnock went searching for Eli. By this stage an off duty police member who is also a volunteer Country Fire Association (“CFA”) member, along with two other CFA members arrived at the scene, Their arrival was in response to being alerted of the incident via their CFA pagers, whilst dining together down the road. Two of the volunteers proceeded to assist Mr Marnock in his search for Eli and Nicola, whilst the other volunteer aimed to isolate the property’s gas flow, as it was suspected that the strong smell of gas upon their arrival, indicated that the fallen tree had caused a significant gas leak on the property.

  10. Whilst this was occurring, members of the Victoria Police, CFA, Ambulance Victoria, State Emergency Service (“SES”), and the Melbourne Fire Brigade (“MFB”) were notified of the incident by the Emergency Services Telecommunications Authority (ESTA).

Eli’s body could be accessed. In spite of this, the paramedics observed that post mortem lividity was present, with Eli’s injuries being incompatible with life.” Active treatment was impossible due to his position, and it was believed that he had passed away on impact of the tree,

At 10:36pm, the paramedics confirmed that Eli was deceased.

A unified CFA and MFB operation was then commenced to make the building safe for Eli’s extraction.

At 11:00pm, the rain fall increased to 13.2mm, with the wind speed dropping slightly to 4km/hr, with the wind gust speed recorded as 9km/hr.!!

At 11:30pm, the rain fall was recorded as 15.2mm, with the wind speed dropping further, to 2km/hr. The wind gust speed was Skm/hr.'?.

At 12:00am, the MFB and CFA continued with their efforts to extract Eli from the wreckage. The rain continued to fall. It was noted to be 16.4mm.4

On 1 March 2015, at 1:10am, Eli was freed from the house. He was assessed by the paramedics in the room adjacent to the partially collapsed carport. It was confirmed that he was deceased.

At 2:08am, in the accompaniment of his father, Eli was carried by one of my representatives to an awaiting vehicle.

Forensic Pathologist, Dr Yeliena Baber of the Victorian Institute of Forensic Medicine performed a post mortem medical inspection on Eli. Dr Baber provided me with a report of her findings. The external examination was consistent with the reported circumstances.

As part of my investigation, Senior Constable Helen Bell provided me with a coronial brief of evidence (“the brief’), The brief contains statements from Eli’s parents, grandfather, employees of the Yarra Ranges Shire Council, consulting arborists, an independent arborist appointed by me, the Bureau of Meteorology, a paramedic, a MFB member, a CFA member, voluntcers who assisted in the initial stages of the rescue, and police members who attended the scene. -

On the evidence before me, I am satisfied that Eli Ian Marnock tragically died as a result of

being crushed by a tree that fell on the roof of his parents’ house during a storm event, and in turn, accept the cause of death as being l(a) Mechanical asphyxia.

Pursuant to section 73(1A) of the Coroners Act 2008, I order that this Finding be published on the internet. .

10 Post mortem lividity is the purple colouration of body parts, except in arcas of contact pressure, appears within 30 minutes to 2 hours after death. It occurs as a result of gravitational movement of blood within the vessels.

COMMENTS

Pursuant to section 67(3) of the Coroners Act 2008, I make the following comments connected with the death:

Tn light of the circumstances of this case, I sought an independent opinion from arborist, Dr Gregory Moore. Dr Moore has taught the principles and techniques of managing urban trees for over thirty years. He is widely recognised for his expertise in arboriculture, plant biology and ecology, and urban horticulture.

On 5 March 2015, Dr Moore inspected the fallen tree.. He concluded that it was unlikely that anyone could have anticipated the windthrow of this tree;"* stating that an ordinary person would not have foreseen it, as there were no obvious reasons to suspect the tree’s stability. Dr Moore stated that because of the tree’s location and apparent good condition, there would have been no obvious reason for calling an arborist to inspect the tree,

In regard to whether a trained arborist would have been able to anticipate that the tree was unstable in the ground prior to the storm event from a routine inspection of the canopy and trunk,!> Dr Moore advised that it is often not possible to tell what is happening with the root system and below the ground from an inspection of the trunk and canopy. He affirmed that in this case, an arborist would have judged the foliage colour and density to be consistent with a healthy tree. Dr Moore also declared that the tree may have been stable at the time of inspection, however the damage to its roots may have occurred after the date of inspection.

Dr Moore asserted that the tree fell as a result of strong winds, and that the damage to other nearby trees suggested that the wind event initiated the windthrow of the tree, and was probably stronger than, or from a direction different to the usual wind events that the tree had previously experienced.

On 17 October 2014, in the inquest of James Robert Winchester, I made recommendations to the Yarra Ranges Shire Council (“the Council”) pursuant to section 72(2) of the Coroners Act 2008. lL advise that the Council responded to these recommendations on 5 January 2015.

Some of the Council’s responses to the recommendations informed that Council would henceforward supply information cards regarding tree safety and reporting risky trees to rate payers with their annual rates notices; would continue engaging with the community on the issue of tree safety with further consideration given to increased advertising through the Council’s website, newsletter, telephone on-hold messaging etc. and that the Council’s main Trees and Vegetation website page has been updated, with the top of the page concentrating on dangerous trees, with images of damaged and dangerous trees identified as examples to assist residents,

I note that inspection of trees is imperative, as the Council identificd that they would respond to resident requests regarding potentially hazardous trees by having the tree

'4 4 windthrow is defined as the uprooting of a whole tree at the interface of the trunk with the soil, which may involve the lifting of roots, the snapping of roots or the failure of the trunk at the soil surface.

‘5 Tn forest ecology, a canopy refers to the upper layer or habitat zone of a tree. The term is sometimes used to reter to the extent of the outer layer of leaves of an individual tree or group of trees.

inspected by a qualified arborist.'!° The health structure of the tree and its target value (i.e.

whether it would hit any construction if it fell) are assessed. The Council identified that if a tree may hit a house it would be allocated as a high target value; meaning it is considered a high priority. Whereas, if it is in an open paddock, it would be rated as a low target value; resulting in it being considered.a lower priority.

  1. Lendorse this approach and would like to encourage those likely to be effected by such events to take advantage of the Council’s initiative in this area :
